DynamoDB: Query Ends With (Guide w/ Code Examples)

To query items where a specific attribute ends with a certain string, you can use the endsWith condition in the KeyConditionExpression parameter of the query operation.

Note that, the attributeName should be the name of the attribute you want to use in the condition, and the value should be the string you want to match the end of the attribute with.

var params = {
    TableName: "myTable",
    KeyConditionExpression: "attributeName endsWith :value",
    ExpressionAttributeValues: {
        ":value": "stringToMatch"
    }
};

dynamodb.query(params, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.log(data);
    }
});
